Rodger: Interesting the climatic differences. Our 20 year old clump of Iris 'Holden Clough' is only 2' wide, growing in richly composted soils. We don't find the flowers muddy at all, although I agree they aren't noticable from a distance like a Japanese iris.

I tore mine out five or so years ago and gave all the pieces away. Let someone else deal with that thug. I can tolerate thuggishness in a garden plant *if* the plant adds significantly to the garden scene, but 'Holden Clough's flowers are of a very muddy color overall and hardly noticeable from a distance. -- Rodger Whitlock Victoria, British Columbia, Canada Maritime Zone 8, a cool Mediterranean climate on beautiful Vancouver Island http://maps.google.ca/maps/…
